Clair A. Stoner 1N VEN TOR,

BY @wm Attorney;

engages a suitable bearing40 which is seated in a suitable recess provided in the carriage or truck plate 26. To assist in retaining the cushion 24 in position, a flange or lip 42 is provided on one surface of the carriagel plate 26, thereby defining a recess in which the cushion 24 is seated.

A shaft or axle 44 extends through the carriage plate 26 and has conventional wheels 46 at opposite ends there of. Of course, suitable nuts 4S may be utilized in association with the terminal portions of the shaft 44 for the firm retention of the wheels in proper position. lt is noted at this point that the shaft 44 extends through the truck plate 26 in a position so that each of the rockershafts 28 and 30,` respectively, are substantially normal to and equally spaced therefrom. The action bolts 28 and 30 are substantially perpendicular to the longitudinal axis of the sole plate.

A construction for supporting front wheels S of the skate is provided. This front wheel support means is identical to the back wheel support means, it being noted that the support means is positioned adjacent the forward end of the flange 12. Since the constructions are identical, it is believed that a detailed description of the forward assembly is unnecessary.

An extension 52 is provided on the flange l2 and has an angularly disposed face thereon. This angularity is relative to the longitudinal axis of the flange 12. An internally threaded sleeve 54 is positioned in the extension 52 for the purpose of receiving a disk 56 detachably therein. This disk has a lug S8 extending therefrom which is threadedly received in the bore of the sleeve S4. The resilient disk 56 is utilized for the purpose of a brake, as illustrated in Figure 6.

The frame member has said shoe-engaging plate 60 integrally formed on the upper surface thereof and this shoe-engaging plate has a slight transverse curve therein as seen in Figure 5, together with a longitudinal curvature arranged so that the toe part is raised as seen by the extension lines in Figure 1 whereby the sole plate is arranged to suit a shoe sole curved as normally would be after wearing the shoe for a time. A conventional shoe 62 is secured to the plate 60 by means of conventional screws 64, rivets, or the like. Of course, if it is found desirable, means for securing the frame member of the skate to an individual, other than the shoe 62, might be utilized. Clamps adapted to be secured to an individuals shoes may be substituted in lieu of the applicants shoe 62 or, if desired, straps may also be utilized. It is noted at this point that it is within the purview of the present invention to substitute skate blades in lieu of the conventional wheels 46 and 50. The particular type of skate blade preferably substituted would be the multi-runner type generally utilized by persons learning the art of skating.

While there has been described and illustrated only a preferred form of the invention, it is apparent that variations may be made without departing from the spirit thereof. Accordingly, limitation is sought only in accordance with the scope of the following claims.

What is claimed as new is as follows:

l. In a skate, a longitudinal sole plate having a fiat rear portion and a transversely curved forward portion, a longitudinal flange integrally formed on the bottom of said plate and extending substantially the full length of said sole plate, the curved portion of said sole plate adapted to accommodate the transverse curvature of the front portion of the skate shoe sole, trucks adjacent the forward portion and rear portion of said flange, each of Awhich includes a truck plate having a wheel shaft mounted therein, a seat formed in said sole plate and a seat formed in said truck plate, a pair of action bolts, each having a threaded portion at one end and a head at the opposite end, one of said bolts being threadedly attached to said truck plate and having its head disposed. in the seat in said sole plate, the other of said action'bolts being threadedly attached to said sole plate and having itshead disposed in the seat in said truck plate, and a pair of cushions having bores accommodating said action bolts and disposed between and engaging said truck plate and said flange.

2. A skate comprising a longitudinal frame member, the upper surface of said frame member forming a sole plate and the lower part of said frame member constituta ing hangers for a pair of spaced trucks, said upper suri face being transversely and longitudinally inwardly curved at the front end to suit the front part of a skate shoe sole having similar curvature and thereby lower the part of the shoe supporting the ball of the foot, a front and rear truck, each truck comprising a plate with an axle, a recess in said plate with one end of a first action bolt rockingly disposed therein, the other end of said rst `bolt being fixed to the lower part of said frame, a second action bolt, a recess in said frame member with one end of said second action bolt rockingly disposed therein, the opposite end of said second bolt being fixed to said plate, a cushion disposed around each bolt, and said cushions reacting on said plate and the lower part of said frame member so that said frame member is cushioned by said cushions at two spaced places for each truck when weight is applied on the sole plate.

3.
